ALFRED E. SMITH, ,OF BRONXVILLE, NEW YORK.

CARRlAGE-AXLE.

SPECIFICATION forming part of Letters Patent No. 258,680, dated May 30, 1882.

Application filed October 20, 1881.

To all whom it may concern Be it known that I, ALFRED E. SMITH, a citizen of the United States, residing` at Bronxville, in the county of Westehester and State ot' New York, have invented new and useful Improvements in Oarriage-Axles, of which the following is a specification, taken in connection with the accompanying drawings, in which- Figure 1 represents a View i elevation of an axle, an axle-boX, a sand-band, and a hub. Fig. 2 represents an end view of hub-box and sand-band or collar.

These improvements relate to certain improvementsinaxlesforvehicles; and they consist in the combination of an axle having bearings that are tapering,'or tapering and parallel, witha pipe-box or bushing eonforning thereto, and with a-sand-band having a flange projecting toward the front end of the axle or box, or a collar adjustcd at its inner ed, and which is passed over the front end of the spindle or axle until it passes beyond the inner end of the axle-box, where it is firmly held by being driven up on the enlarged tapering part of the axle, which taper serves the purpose of resisting the further novement of' the sand-band or collar toward tle inner end of the axle, and whicl allows the axle-box to be better fitted to its bearings by grinding it with suitable material to its proper place of bearing' before the sand-band or collar is adjusted,and making the axle stronger at its root than it would he if it were straight, the sand-band being held in place by its pressure around the axle, and by the front edge of its projecting fiange abutting against a recessed bearing in the inner end of the hub and forming a cup in which the inner end of the box revolves, the axle-box being held upon its spindl'e, with its inner surface abutting against the inclined bearings of the spindle, by a screw nut screwed upon the screw-threaded end of the spindle or axle, as more fully hereinafter set forth.

In the accompaiying drawings, letter A indicates the hub; letter G, an axle-box. Letter L indicates the shank of an axle, and letter D the spindle thereof, having an enlarged tapering bearing, E, an incline, F, and a diminished spindle, H. Letter K shows the screw-threaded end of the spindle. G shows (No model.)

the nut. LetterBindieates the send-band, and b its projecting flange.

The sand-band or collar is nade of a separate piece of metal. Itmay be cast or wrought, and is driven up or secured upon the axle at or near the inner end of the axle-box. It may belocated beyond the inner end of the aXle-box for the purpose of holding a washer or packing to prevent the flow of oil, or to deaden the concussion caused by the thrust of the box against the shoulder of the axle.

I am aware that sand-bands have been used when they have been applied to hubs with their fianges projecting from the hubs and over the collars of the aXles, and also when the collar has been made solid to the axle and a recess cut into it, to receive the inner end of the box; but the first way is defeetive and gives only partial protection, and the second way is expensive and prohibits the box from being perfectly fitted to its bearings on account of the material used in grinding the box to the axle packing and clogging between the end of the box and the Collar, thereby preventing a pcrfect bearing to.be made, whercas my way, being detachable and adjustable, can be applied after the box has been properly ground or fitted to its bearings, making a cheaper and stron ger a-xle. Therefore I clain1-- l. An axle with an enla'ged taperingjonrnal-bcaring at its rearend, up which a detachable and adjustable flanged send-band or collar is pressed or driven until it is placed beyond the inner end of the axle-box.

2. A detachable flan ged sand-band or collar which is driven up on thetaperof the enlarged bearing,` at the rear end of the axle until it is beyond the rear end ot'the axle-box when said box is properly fitted to its'axle, and its inner end revolves within the cup formed by the *fiange projecting toward the front end of the axle-hox or against the collar which it may abut.

In witness whereof I have hereunto subscribed my name and affixed my seal in the presence of two subscribing witnesses.

ALFRED E. SMITH.
